Abstract	This study aims to investigate the immunohistochemical expression of mammary serine protease inhibitor (maspin) and CD138 in primary ovarian high-grade serous carcinomas (HGSC) as compared to low-grade serous carcinomas (LGSC) and clear cell carcinomas and investigate if the studied markers have a correlation to International Federation of Gynaecology and Obstetrics (FIGO) stage, Ki67 proliferation index, and to each other. Maspin cellular location varied significantly between studied groups with only nuclear expression seen in 46.7 % of LGSC group, mixed nuclear and cytoplasmic in 13.3, 28.6, and 20 % of LGSC, HGSC, and clear cell carcinoma, respectively, and was only cytoplasmic in 26.7, 71.4, and 80 % of LGSC, HGSC, and clear cell carcinoma, respectively. Mean maspin and CD138 counts were significantly higher in HGSC and clear cell carcinoma compared to LGSC. Both maspin and CD138 scores varied significantly between studied groups and were positively correlated with adverse prognostic factors in studied carcinomas including FIGO stage and Ki67 proliferation index. Besides, both maspin and CD138 had significant correlation to each other. These findings suggest that epithelial cytoplasmic expression of maspin and CD138 may have a significant role in tumorigenesis in ovarian high-grade serous carcinomas and clear cell carcinomas; these markers may regulate tumor cell proliferation, and their significant correlation to each other may suggest that CD138 probably induces maspin expression to protect tumor growth factors from being lysed by proteolytic enzymes.
